StemCell Therapy

If cupid had studied neuroscience, he’d know to aim his arrows at the brain rather than the heart. Recent research suggests that for love to last, it’s best he dip those arrows in oxytocin. Although scientists have long known that this hormone is essential for monogamous rodents to stay true to their mates, and that it makes humans more trusting toward one another, they are now finding that it is also crucial to how we form and maintain romantic relationships.

Muscle stiffness is a major clinical feature in Duchenne muscular dystrophy (DMD). DMD is the most common lethal inherited muscle-wasting disease in boys, and it is caused by the lack of the dystrophin protein. We recently showed that the extensor digitorum longus (EDL) muscle of mdx mice (a DMD mouse model) exhibits disease-associated muscle stiffness. Truncated micro- and mini-dystrophins are the leading candidates for DMD gene therapy. Unfortunately, it has never been clear whether these truncated genes can mitigate muscle stiffness. To address this question, we examined the passive properties of the EDL muscle in transgenic mdx mice that expressed a representative mini- or micro-gene (H2-R15, R2-15/R18-23/C, or R4-23/C). The passive properties were measured at the ages of 6 and 20 mo a...

Potent growth-inhibitory effect of a dual cancer-specific oncolytic adenovirus expressing apoptin on prostate carcinoma.
Int J Oncol. 2013 Mar;42(3):1052-60
Authors: Zhang M, Wang J, Li C, Hu N, Wang K, Ji H, He D, Quan C, Li X, Jin N, Li Y
Abstract
Apoptin is a chicken anemia virus-derived, p53-independent, bcl-2-insensitive apoptotic protein with the ability to specifically induce apoptosis in various human tumor cells, but not in normal cells. To explore the use of apoptin in tumor gene therapy, we assessed a recombinant adenovirus expressing the apoptin protein (Ad-hTERTp-E1a-Apoptin) in order to determine its lethal and growth-inhibitory effects on PC-3 and RM-1 cells in vitro and its antitumor effect on solid tumors in vivo....

Authors: Kurosaki T, Uematsu M, Shimoda K, Suzuma K, Nakai M, Nakamura T, Kitahara T, Kitaoka T, Sasaki H
Abstract
In this experiment, we developed anionic ternary complexes for effective and safe ocular gene delivery. Ternary complexes were constructed by coating plasmid DNA (pDNA)/polyethylenimine (PEI) complex with anionic polymers such as ?-polyglutamic acid (?-PGA) and chondroitin sulfate (CS). The cationic pDNA/PEI complex showed high gene expression on the human retinal pigment epithelial cell line, ARPE-19 cells. The pDNA/PEI complexes, however, also showed high cytotoxicity on the cells and aggregated strongly in the vitreous body. On the other hand, the anionic ternary complexes showed high gene expression on ARPE-19 cells without such cytotoxicity and aggregation. Afte...

Research on human beings has expanded greatly due to progress and the evolution of society as well as customs. Not only the unceasing development of research on human beings, but also interference in the beginning and end of life with homologous and heterogonous human reproduction, surrogate motherhood, cloning, gene therapies, eugenics,euthanasia, dysthanasia, orthothanasia, assisted suicide, genetic engineering, reassignment surgery in cases of transsexuality, the use of recombinant DNA technology and embryonic stem cells, transplantation of human organs and tissues, biotechnology and many other scientific advances. Scientific progress goes faster than the real needs of human beings, who are the final recipient of the entire evolutionary progress. Hence, there is the need to scrutinize w...

After the first description of a patient recognized as a MPS case was made in 1917, several similar cases were described and identified. Observations reported in the middle of the twentieth century concerning the presence of acid mucopolysaccharides (later called glycosaminoglycans, or GAGs) in tissues and especially in urine of patients were instrumental in providing an identity for these diseases, which became referred as "mucopolysaccharidoses" (MPS). In the late 1960's it was demonstrated that MPS were caused by defects in the breakdown of GAGs, and the specific enzyme deficiencies for the 11 types and subtypes of MPS were identified thereafter. Genes involved in the MPS were subsequently identified, and a large number of disease-causing mutations were identified in each one. Although ...

Scientists and engineers dream about big advances that could change the world, and then they try to create them. On the following pages, Scientific American reveals 10 innovations that could be game changers: an artificial alternative to DNA, oil that cleans water, pacemakers powered by our blood, and more. These are not pie-in-the-sky notions but practical breakthroughs that have been proved or prototyped and are poised to scale up greatly. Each has the potential to make what may now seem impossible possible. -- The Editors

In the womb, a ball of identical cells gives rise to varied cell types that ultimately form highly ordered structures and then the full panoply of organs in the human body. The process advances according to an internal biological script that directs each fold and crease of tissue to assume exactly the proper shape and dimension.

Yoshiki Sasai is not just an ordinary tissue engineer who tries to coax stem cells to grow into fully formed bodily structures. It is true that Sasai has made his mark by taking on big projects like using stem cells to whip up a retina, cortical tissue and the cerebellum, involved with balance and movement. But his research has gone deeper by delving into the way stem cells organize themselves into complex structures under the influence of genes and the prenatal environment. Read a profile of Sasai here to accompany “ Grow Your Own Eye ,” Sasai’s own account of growing a retina in the November Scientific American .
